About this plugin
This plugin was previously called Spectra. It’s now Spectra Legacy. Nothing on your website has changed.
Your blocks, pages, settings, and content all continue to work exactly as they did before. There’s nothing to migrate and nothing to configure.
Spectra Legacy vs. Spectra Blocks
We’ve split Spectra into two products.
Spectra Legacy is this plugin — built for existing Spectra users. It receives security and compatibility updates and full support, but no new features. Spectra Blocks is a new, separate plugin where all new feature development happens, aimed at new installs and anyone who wants ongoing additions. If you’re already using this plugin, no action is needed; installing Spectra Blocks is entirely optional whenever you’re ready.
If you’re already using this plugin, you don’t need to do anything. If you want new features as they’re released, you can install Spectra Blocks separately, whenever you’re ready. There’s no deadline and no required migration.
What’s included
Spectra Legacy includes the full block library your site is already built on: layout tools, content and post blocks, form and SEO blocks, social blocks, and site tools like Popup Builder and Coming Soon mode.

Questions
- Why is this plugin now called Spectra Legacy?
We split Spectra into two products: Spectra Legacy (this plugin, for existing users) and Spectra Blocks (a new plugin for future development). The rename reflects that split — it doesn’t change how this plugin works.
- Do I need to do anything after this update?
No. This is a naming change, not a functional one. Your site continues to work exactly as before.
- Will my existing website break?
No. Spectra Legacy is fully backward compatible with everything built using the plugin before the rename.
- Do I need to migrate to Spectra Blocks?
No. There’s no required migration and no deadline. Spectra Blocks is a separate, optional plugin. You can keep using Spectra Legacy indefinitely.
- Is Spectra Legacy still supported?
Yes. It continues to receive security updates, compatibility fixes for new WordPress and PHP versions, and standard support.
- What’s the difference between Spectra Legacy and Spectra Blocks?
Spectra Legacy is the version you already have — stable and unchanged in how it works. Spectra Blocks is where all new features are being built going forward. See the comparison above.
- Can I use both plugins on the same site?
Yes — and during a transition, most people do. Existing pages keep working on Spectra Legacy while you build new pages in Spectra Blocks. Each plugin only loads assets for the blocks a given page uses, so running both isn’t a heavy performance tax. It’s not meant to be a permanent setup: once your site no longer has any Legacy blocks, you can deactivate Spectra Legacy.
- What happened to the Spectra AI block?
It’s now called ZipAI. It still works in Spectra Legacy. New AI features are being developed in Spectra Blocks.
